Winona, Min. (WKBT) -

An environmental-quality committee in Winona wants closer monitoring of frac sand mining in the city.

The Citizen's Environmental Quality Committee is recommending four or five air quality monitors along truck routes in the city.  The Winona Planning Commission is expected to consider the recommendations at its next meeting. One Committee member says more monitoring will benefit residents and the industry.

The committee's recommendations are not binding on the city planning commission.
